` My present ,inventionrelates to weather strips for slidingwindowsashes commonly referred to in the trade asdou'ble-chung windows.l' if This invention provides for each-sideotSeJ sliding sash a weatherstrip v,device comprising two members,V one of which is applicable tothesash and the othery of which yis applicable to a iframe in which thesashis slidably im mounted. These vtwo members areconnected byinterlocked-elements forcom'monmovement, at their point otconnection,exceptta longitudinal sliding movement of the fsash,

member element in respecttotheframe mem- 15 ber element to permit therequired. raising and lowering movements Ao-tlie sash in ,respect to theframe. The Weather 4 strip device is constructed and arranged for:self-adj ,ustnient to permit varying changes intherelativelit 20 oi thesash in the frame dueto shrinkage or egrpansion of the sash, to`thebowing"of the frame or to the warping, offeitherfof the sash'Stiles. As is well-known changesinjtheinois ture contents of a'sash andframe, differences l25 in humidity and temperature between theontsideand insideof a window, and theunskill ful fitting and yinstallation ofasash in'its frame all i combine to 4produce ,a constantly changingrelative t ofthe sashinthe frame.

In order to make possible the use "of the above method ofinterlockingtwo weather aStrip members7 one of which isattlachedjto asash and the other of which is attacheilv tothe trame, it is necessarytolprovide"twogadjust ments on account of the ,above varying changes ofthe sashwithA relation tothe fname. One of these adjustments must permitthe interlocked members to adjustthemselves -prfecy t0 the Variations-in the Crack-'or opening bet-Ween the sash and lthe frame caused byswelling, shrinking or iitting ofthe sash byj-a carpenter @The other,oftliese Faldjustments mustpermit thefnterlockedfmembers to adjust-themselves to variations in clearance between the' faces ofthe sashandthe sides of the 'frame channelrunwayinwliieh the sash is mounted,caused` usually l by the warping or4 bowing of the' sash.

Figs. 2 to 9, inclusive, are fragmentary detail views in horizontalsection taken through the lower sash and frame lof a double-hung windowandshowing still other forms of the weather strip device; and y Figs. 10and 11 are fragmentary detail views showing different forms for theinterlocked elements of the weather strip'device.`

The numeral 12 indicates the wooden frame of a double-hung window havingan inner channel runway 13 and an outer channel runway 14 formed,respectively, by an inner stop 15 and a parting strip 16 and said'stripand an outerv stop 17. Said parting strip 16 is removably mounted in agroove 18 in the frame 12. A lower sash 19 andan upper sash 2O aremounted in the runways 13 and 14, respectively, for vertical slidingmovement. It is important to note that the working fit of each sash inits runway is such that said sash is freev for a limited lateralmovement (at right angles to the plane of the sash) insaid runway and alimited horizontal movement in the plane of said sash and in respectthereto.

" The parts thus far described are the same in all figuresillustratedand have thesame reference characters. The weather strip devices for theupper and lower sashes are the same and except in Fig. 1 only the lowersash is'illustrated.4 j

All of the different forms of weather strip devices, illustrated, arecapable of two distinct' and important functions, aside from forming aweather-tight joint between the sashY and frame,fto wit; saiddevice isselfadjusting to permitthe sash to move lateral-V lyin its runway orhorizontally in the plane of the sash, as will hereinafter be more fullydescribed. l

y Referring first to the weather strip device, shown'in Fig. 1, the samecomprises a sash member or strip 21 and a frame member or strip 22. Saidsash member 21 is mounted in ashallow rabbet 23 in the face of the sash19 Y adjacent to the parting strip 16 and is secured by nails X to saidsash. On the outer edge portion of the sashincmber 21 is a tubularelement 24 with which the frame member 22 is'interlocked, aswillpresently appear. This tubular element24 extends the full length ofthe sash member 21 and is formed rby rolling said member tosubstantially a full circle in which its free-edge portions is spacedfrom the body thereof to leave a narrow longitudi-- nal entrancepassageway 25. The sash 19 is further rabbeted at 26 to receive thetubular element 24 and which element is substantially within the body ofsaid sash.

- The frame member 22extends substantially tothe full width of therunway 14 andv is secured by nails X to the frame 12 adjacent to theinner stop 15. Said framemember 22 parallel to the sash` member 21 andin opposing relation. The frameV member 22, toward the terminal end ofits fold 28 extends laterally and to an extent pivotally through thelpassageway 25, and formed therewith is a tubular element 29 telescopedin the tubular member 24 with a working fit. The interlocked elements 24and 29 connect the sash member 21 to the frame member22 for commonlmovement, except free longitudinal movement of the tubular element 24 onthe tubular element 29, to permit the required raising and loweringmovements of the sash 19.` It will be'noted that the width of thepassageway 25 will permit limited relative turning movement of thetubular elemember 22 to permit lateral movement of the sash 19 inthe-runway 14. ,Y y

The 'weather strip device for the upper Sash 20 is identical with theweather strip device just described and th-e parts thereof Y have thesame reference characters. Rabbets in the several illustrations of thesash 19 are kdesignated by the same reference numerals.

In the construction shown in Fig. 2, the sash member and the framemember are designated by the numerals 30 and 31, respectively, said sashm-ember 8O is like sash member 21 and the interloclred elements whichconnect the sash member 30V and the frame member 31 are like those shownin Fig. 1 and dcsignatedby "the numeral 32. The frame member 31 issecured by nails X to the frame 12, between said frame and parting strip16, andcomprises a relatively long U-shaped fold 33 which ext-endstransv versely in the runway 13, a second relatively yshort U-shapedfold 34, which extends into sash.

the .sash 19 in its planeandin respect tothe :trame v'12, )and thefold35=is self-'adjusting to'fpermit lateral movement ofthe `sash 19 inthe frame 12V` Y .The weather strip device shown in Fig. 3 `comprises asash membere36and a frame member` 37, theformer; of which-isxin the formof an .angleone langeofnwhichais lin the rabbet 23 and secureduby nails.X to the sash 19and the otherlfla'nge thereof `is likewise. secured totherespeetizve Yedge `of said f i Interloeked elements 38which connectthe sash member 36 and 1frame' member 37 'are .identicalwith .thestructure.4 shown yin Fig. 1 with Athe exception .that the entrancepassageway is substantially at right angles to the entrance passagewayand faces the frame 12. The formation of the frame' member 37 is quitedifferent from that shown in Figs. 1 and 2 in that in place of a flexingor yielding movement to permit horizontal movement of the sash 19 in itsplane, this movement is accomplished by a slip joint in the frame member37. Said frame member 37 has a U-shaped fold 39 that corresponds to thefold 28, and the anchored section 40 of the frame member 37 is in theform of an angle seated in the groove 18 and secured by nails X to theframe 12 under the parting strip 16. The anchored section and the foldedsection of the frame member 37 have overlapping sliding contact, thelatter with the former, that affords the slip joint 41 heretoforereferred to. Obviously, the fold 39 is self-adjusting and permitslateral movement of the sash 19 in its runway 14 and the slip joint 41permits horizontalmovement of said sash in the plane thereof.

ln the construction shown in Fig. 4 thesash member and frame member aredesignated, respectively, by the numerals42 and 43 and said sash memberis substantially like that shown in Fig. l except that the interlockedelements are rectangular in crosssection and indicated by the numeral44. The frame member 43 includes a U-shaped fold 45, an anchored section46 and a slip joint 47 therebetween and like the slip oint shown in Fig.3.

Fig. 5 shows a construction like that of Fig. 1 except that the framemember has a slip joint in place of a flexing section. In thisconstruction the numeral 48 indicates the sash member, the numeral 49the frame member and the numeral 5() indicates the interlocked elementsbetween the members 48 and 49. The frame member 49 includes a U-shapedfold 50 which corresponds to the fold 28 and the anchored sectionthereof is ytwo-ply and in the form of an angle, one

flange of which rests on the bottom of the runway 14 and is secured bynails X to the frame 12. The plies of the other ange of the anchoredsection of the frame member -lateral movement ofthe sash .same as thatshown in Fig. 8 with -tion that :the interlocked elements 'v connect thesash member -64 .and uneinber, areyoval-shaped in cross-section;

@In Fig.-6 the sash and 'frame members and the interlocked elementsaredesignated:v by Vthe numerals 52,53 and 54, respectively.

The sash member 52 and interlocked elements' 54 are the same, as shownin Fig. =1, the fold 55, slip joint 56 are the same as that shown inFig. `4, and theattachment of the frame Vas member 53 to the frame 12vis the same as that `shownin Fig. 3.` f Fig. 7A 'safragmentaryperspective 'view thereof'is foldedover lthe fold section 55 at 5 7 toprevent saidfold section from followfing the. sash section 52 .when thewindow. is

Also while Fig. 7-,shows the lower sash only, similar means are employedwith the upper sash, the fold 57 being at the bottom and the foldsection being held by thehead of the fra-me instead of the sill.

The structureY shown in Fig.- 8 is the same Aasthat shown inxFig. 6`except :as tothe attachment of the frame memberto the'frame `12. 'In:this structure the sash member and the frame member, `the interlocked'elements .that connect the same, vand the slip joint, are indicated, x62, inclusive.

' In Fig. 9 thestrueture is the same as that respectively, bythe.numerals A58 to shown in. Fig. '.8 with the exception 'that theanchoredsection o-f the frame member is provided with a second foldwhich gives said member the required lliexibility topermit 19 in litsrunway 14. The numeral .58 indicates the sash member, 59 ytheinterlocked elements and 60 the frame member which has three-U-shaped ffolds 61,'62 .and 63. The fold 61 is formed 4.with the respectiveinterlocked element 59 and the folds 162 and 63 are formed with kthe:anchored section of the frame member 60. The folds 61 and 62 areinterlocked to Vform a slip joint 64 which serves the same purpose asthe slip joint heretofore referred to and -the fold V63 gives therequired flexibility to `the frame member and permits lateral movementof the sash 19 inthe runway 14.
